| 20080283300 | DRILLING RIG AND VIBRATION DAMPENING SUPPORT FRAME - A drill rig includes a carrier platform and a drilling unit carried by the carrier platform. The drilling unit includes a support frame pivotally mounted on the carrier platform, a slider frame slidably mounted upon and surrounding the support frame, a drilling support mechanism mounted on the slider frame, a drill portion rotatable relative to said drilling support mechanism, and a power means for effecting rotation of the drill portion. When a drilling operation is to be effected, the support frame is pivotally moved to assume a substantially vertical position, and the slider frame is slidably moved along the support frame to an operative position for effecting a drilling operation. The support frame comprises two main tower beams partially covered in High-Density Polyethylene (HDPE) plastic, and the slider frame which surrounds the support frame comprises plates positioned on the top and bottom of the tower beams, with inside and outside joiner plates encasing the sides of the support frame. Each of these plates are covered with HDPE plastic on the surface which contacts the support frame. In this manner, vibration from the drilling operation is substantially reduced. | 11-20-2008 |
| 20090044983 | Portable Concrete Boring Machine - A portable boring machine for cutting holes in a cutting surface is provided. The portable boring machine includes a vacuum system to secure a front end of the portable boring machine to a cutting surface, a hydraulic boring sub-assembly, which includes a hole saw to cut holes in the cutting surface, a water cooling/lubrication system to provide cooling and/or lubrication to the hole saw during the cutting process, and a control system to control the operation of the portable boring machine. The portable boring machine also includes multiple power-driven wheels. The wheels are attached to a bottom portion of a frame and are powered by an engine, which is mounted within the frame. | 02-19-2009 |
| 20100319999 | Device for an Electromechanical Hoisting Machine, Especially for Use When Drilling Oil and Gas Wells - A device for an electromechanical hoisting machine ( | 12-23-2010 |
| 20110048808 | FEED UNIT - The present invention pertains to a feed unit ( | 03-03-2011 |
| 20130206480 | Human-Powered Borehole Drill - A human-powered borehole drill bridges the gap between large drilling rigs and the other less-effective manual methods. Intended mainly for developing countries, the design is affordable and also extremely simple, as very little product support or spare parts will be needed. The drill uses conventional drill pipe and drill bits allowing the drill system to mimic more conventional methods of drilling and existing hardware to maintain uniformity in drilling and easier access to more drilling products. | 08-15-2013 |
| 20130233625 | Powered Auger Support Assembly for a Vehicle - A powered auger support device is provided having connection to a vehicle, a trailer hitch receiver on a vehicle, or the bed of a trailer, whereby a powered auger is slideably supported along an upright rail by way of a winch controlled by an operator. The device comprises a support structure having an upright rail, an auger support frame, and a pulley and winch system for raising and lowering the auger support frame. The auger support frame supports the handles of a stand-along auger and is pivotably supported along the rail, permitting the support frame to rotate with respect to the frame for placing the auger working end at different angles or in a horizontally stowed position. An embodiment of the upright rail contemplates a rotational hinge that places the auger support frame outside of the vehicle wheel tracks or outside of the bed of a trailer during use. | 09-12-2013 |
| 20140291030 | Replaceably Lined Cable Guides and Tensioning Roller for Drill Line Slip and Cut Operations on a Drilling Rig - Cable guides for overhead support of drill line on a drilling rig during a slip and cut operation feature replaceable liners of wear material supported by a re-usable base. A tensioning roller added to the draw-works resides outward from the periphery of the draw-works drum and is spring-biased toward same into order to force the incoming drill line against the periphery of the drum. | 10-02-2014 |
| 20150372492 | REPOWERING SCR RIGS TO AC TECHNOLOGY - A power delivery system that includes at least one generator where the generator is positioned to provide AC power and a rectifier, where the rectifier is electrically coupled to the generator. The rectifier is positioned to convert the AC power to DC power. The power delivery system further includes an SCR, where the SCR is positioned to receive DC power from the rectifier. The SCR is adapted to selectively switch a DC motor from an off to an on position. The power delivery system also includes an inverter. The rectifier is positioned to receive DC power from the rectifier and to supply AC current to an AC motor. | 12-24-2015 |
